Alternative to a global VLA

I have been working on my primitive game, and up till now I have been loading verteces and triangles form OBJ files into linked lists. I went to change the program to use VLAs instead, but ran into trouble. I need the VLAs to be global, as it is a glut program, but the C standard does not allow VLAs to have file scope. Is there a loophole or something I can exploit to allow me to use VLAs or is there some alternative? Will I just have to hard wire the array sizes in? What do you guys use for storing OBJ data?
